how to get the path of a module (myself) ?

hello,

I've pictures stored in a path relative to my python source code.
To get a picture, I need to know what path I'm on in each python module.
I thought __file__ would do the job,
but apparently I didn't read the documentation carefully enough,
because file is the path to the module that called my module.

Any ways to get the path of "myself" ?

thanks,
Stef Mientki

I'm not sure what you mean. I just did a quick test.

# File: C:\Quick test\child.py
print "name is %s" % __name__
print "file is %s" % __file__

# File: C:\Quick test\parent.py
import child

print "name is %s" % __name__
print "file is %s" % __file__

# Output:
name is child
file is C:\Quick test\child.py
name is __main__
file is C:\Quick test\parent.py

Yes, that's what I (and many others) thought,

This ain't the official way... but the hackers way.....

Check site.path (import site)...

If your module got loaded, and it's own succinct directory or .egg, then
it will have been added to site.path. 

You might have to parse the values in site.path but we're only talking
a few lines of code because you already know the package name.

If not, there's another way through pkg_utils...

Regards

David

Eeek.

> head -999 foo/*
==> foo/__init__.py <==
import pkg_resources
print pkg_resources.resource_string(__name__, "bar")

==> foo/bar <==
bar

> python -c "import foo"
bar

Make a "def load_resource" from that print line and you're done.

How to get the path of current running python script?

I tried the following
 
>>>> getFilePath = lambda name: os.path.normpath('%s\\%s' % (sys.modules[name].prefix, sys.modules[name].__name__))
>>>> getFilePath('__main__')
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "<interactive input>", line 1, in <lambda>
AttributeError: 'module' object has no attribute 'prefix'
>>>>

 Can you help me?
